Is there a way I can evaporate the solvent without oxidizing the DMT? In my first extraction I evaporated with a fan blowing hot air across my N.P. solvent in the sun which, as it turns out, is a potent combination of producing DMT N-oxide. Is there a way to evaporate the solvent without oxidizing any of the DMT? Or even at least minimizing it? I think my best bet is to slowly evaporate in a narrow jar to reduce surface area.

Are you evaporating naptha or something else?

In either case I would recommend you read this thread and also this one which I have been meaning to make for a while and your post gave me the motivation to finally do it, haha.

you could evaporate under an inert gas flow, probably not worth the trouble though. Evaporating under reduced pressure with no air flow should protect it fairly well. If vapor is produced from your solvent faster than oxygen diffuses through the layer of vapors over your solvent it'll protect your DMT from contact with oxygen. Heat's bad as it both makes the DMT and O2 more reactive and creates a convection current exposing the solvent to more O2

Why some people don't want oxidized DMT? Sure it might look yellow, but it's just as good...

I can tell you tele that DMT oxide is terrible. It is incredibly harsh. It's not that it is yellow crystals, but a gross dark yellow oil. I just reduced a large amount of it from my first extraction and am now getting crystals.

Very good information q21q21. So DMT acetate can be vaporized/smoked much like the freebase? I might not even bother with evaporation or frezzing then. Do you know about DMT citrate? I have pure citric acid but it might cause some problems since it is triprotic.

There is one flaw in your vinegar experiments though, you have no control. It's possible that there is a substance that is soluble in vinegar but even more soluble in non-polar solvents which could give you those results. I think that I will do a freeze precipitation soon though. The solvent I am using is mineral turpentine. According to the msds and wikipedia it is more than 60% aromatic hydrocarbons and 20-40% naptha.

Rhave, I actually considered evaporating in a high/pure CO2 environment. I think to get vapor from my solvent produced faster than oxygen can get in is to maybe have the solvent at the bottom of a bottle with a narrow opening (e.g. a wine bottle). The solvent vapors would fill the bottle and then leave out the top of the bottle. The narrow opening would speed up the flow rate for the vapors which would make it difficult for air to enter the bottle. Am I right?

Igel, did you have a 'control' batch where you redissolved and repulled without doing the reduction to compare? often oils are not n-oxide, just some plant oils or traces of solvent trapped under by surface tension of concentrated oil, preventing dmt from crystallize. So just re-a/bing would probably already help a lot even if n-oxide wasnt there.

Did you use zinc and acetic or hcl acid? or another reducing agent?

Well endlessness, I am fairly sure I had n-oxide and this is why:

My yellow oily waste was the results of evaporating with heat and a fan - this produces lots of DMT N-oxide. My yellow remnants were soluble in water, as is DMT N-oxide. Right now it is worthy to note that a POLAR substance was initially pulled with a NON-POLAR substance, which indicates that some sort of reaction has occurred to make it go from non-polar to polar. I added some citric acid and zinc (galvanized nails) to the n-oxide and left it to sit for a while. I basified with sodium carbonate and my pulls so far are yielding yellowish crystals.

So yeah, mission success. I'm thinking it would be good to add a reducing agent in acidification of A/B extractions to yield more DMT.

... and no, I did not do a control. It was more of a salvage operation than an experiment. The extraction the oxide came from was more of an experiment where I was just trying to see if the tree I was using contained DMT and/or if I had a good method.

But yeah, reducing n-oxide if pretty much just an A/B with zinc.
